Prevent Material Marking by Eliminating Dancer Arm Bounce with a P/A Loop Control or Stock Detector
Bouncing Dancer Arms often dent, scratch, and crease delicate, prepainted, or highly polished stock. To eliminate this problem, P/A offers several solutions.
The LC-2 is an ON/OFF Electronic Limit Switch
Sensing vertical movement in a slack loop of conductive material. Spring probes maintain smooth stock delivery between the adjustable upper and lower limits.
Reduce Die Breakage and Machine Downtime
Prevent the smashup of ONE die and this sensor pays for itself. The P/A Stock Detector uses a resistance-sensing controller to monitor material position as it enters the press or moves through the die.
The RF System Uses a Shielded Antenna
And a Radio Frequency Field to sense conductive material. As the loop changes height, the radio signal changes in response causing the variable DC drive of the Reel or Straightener to maintain a constant loop.
The P/A Ultrasonic Loop Control Utilizes Sonar, Or "Echo Location"
To determine and maintain a constant loop height. This gives the operator the flexibility of using the longer loops required when stamping long progressions.
